1200 300 001 MAN Compatible Twin Cylinder Compressor

What does a twin cylinder compressor do?

This twin cylinder air compressor serves as a critical engine-driven component within the air brake system of heavy commercial vehicles. By utilizing two piston-cylinder assemblies, this unit delivers a higher air output compared to single-cylinder versions, ensuring faster reservoir charging. It is engineered with high-strength components to withstand the intense pressure and temperature cycles required during operation.

Vehicle and engine compatibility

This unit is designed for compatibility with MAN and Volkswagen Truck vehicles. It is also fitted to other heavy commercial vehicles requiring high-volume air delivery, such as multi-axle tractor units or tipper trucks. The design includes an ESS feature and a water-cooled valve plate to maintain optimal thermal stability during heavy-duty service.

Installation and maintenance guidance

For professional installation, technicians should verify the M10 x 1.0 air unloader port and the M26 x 1.5 air outlet port specifications. The unit features a through drive mechanism and specific port sizes including a Ø 34.5 mm air inlet and M16 x 1.5 water ports to ensure seamless integration into the existing pneumatic system.

Troubleshooting and selection

Regular inspection of the water inlet and outlet connections is recommended to prevent leaks that could compromise braking performance. Consult your authorized distributor to ensure exact fitment for your specific engine configuration.
